Application filed December 6, 1913. I Serial No. 804,994.

To all whom-it may concern:

Be it known that I, OTTO B. JOHNSON, a subject of the King of Sweden, having declared, my intention of becoming a citizen of the United States, residing in Wilmington, county of Newcastle, State of Delaware, have invented certain Improvements in Car- Roofs, of which the following is a specification.

My invention relates to certain improve ments in the construction of the roofs of steel passenger cars in which there is a clear story.

One object of my invention is to so construct the roof thatthe upper section of the carline will be carried down at the sides of the clear story and will be secured to the lower section of the carline.

A further object of the invention is to make the extending portions of the upper section of the carline of a greater width than the main portion thereof, so as to allow for themovement of a window between the inner and outer, walls.

A still further object of the invention is to extend the upper roof sheet down to the lower roof sheet, forming the outside deck, which is punched and pressed to receive the screen.

The invention also relates to details which will be fully described hereinafter.

In the accompanying drawings :Figure 1, is a transverse sectional view on the line w.w, Fig. 3, of a car roof illustrating my invention; Fig. 2, is a transverse. sectional view on the line bb, Fig. 3, illustrating my invention; Fig. 3, is a side view of a portion of a car roof made in accordance with my invention; Fig. 4, is a sectional plan view on the line 0-0, Fig. 3; Fig. 5, is a sectional view on the line d-d, Fig. 1; Fig. 6, is a view illustrating amodification; Fig. 7, is

an enlarged sectional view of a portion of Fig. 1, showing the detailed method of hangs ing the clear story window sash; and Fig. 8,

invention applied to an ordinary car roof. Referring to the drawings, 1, 1 are the upper section of the roof carlines extending over the clear story of the car and spaced apart as shown. 7

2, 2 are the lower section of the roof carlines and 3, 3 are the side frames of the car. The upper sections 1, illustrated in Fig. 1, extend in a single piece over the clear story and at each side thereof as indicated at 4,

and these side portions are of a greater width than the roof portions 1. In fact, they are of a width which will allow the car builder to insert a movable window and a screen between the inner and the outer edges of the portions 4, as illustrated in the drawlngs.

In some instances, the side portions may be made of a separate piece riveted to the roof portion, as indicated in Fig. 6, in which 4*, 4 are theseparate side pieces and 1 is the main upper section of the roof carline flanged and bent, as shown, and united at 5*. In this instance, the flanges of the side sections extend between the flanges of the main roof section. The side members of the upper section of the carlines extend past the lower sections 2 and are riveted thereto at 5, making an exceedingly. strong and substantial structure. v

The upper roof sheet 6 extends over the top of the upper sections of the carlines and on eachside thereof down to the lower roof sheets 7 and overlaps the flange 8 thereof, and the lower roof sheets 7 lap over the side sheets 9. The upper roof sheets are punched to form openings 10 and are pressed at the edges to form flanges 11 to which the screens 12 are attached. [The screens .extend over the flanges and are secured thereto-by wires or other means. The screens, being on the inner side of the roof sheet, are protected to a certain degree.

The construction above described avoids the making and fitting of special screens for the clear story openings.

The casing 21 for the window is applied when the roof is placed in position and takes the same rivets. This construction avoids screws, which are expensive.

The deck web plate forms the inside finish .and gives a bond between the upper and lower sections of the carlines, making these important members practically asingle element. I

13 is "the ceiling and 14, 14 are the side plates of the clear story which are punched to form the window openings 15. These side plates underlap the upper ceiling, as shown, and the lower sections of the roof plates 16 extend under the lower carlines, and a finish strip 17 is secured at the junction of the side plates 14 and the ceiling. The finish strips 18 are placed at the junction of the ceiling 13 and the side plates 14, as shown in Fig. 2.

The window sash 19 is secured in the walls flanges. This makes a very simple construction.

The side members 4 can be made of any width desired, according to the size of the window opening and the character of the sash to be applied to the opening, and while the upper sections of the carlines and the side members are made in a single piece, as shown in Fig. 1, they may be madein two pieces riveted together, as illustrated in Fig. 6.

I preferably form an opening 20 in the web of the upper carlines, as indicated in the drawings, for the purpose of decreasing the weight without materially weakening the same.

The sill plate 21 of the window casing is inclined toward the center, as shown, and an opening 22 is formed in the outer roof plate to allow for the escape of any water which may accumulate between the screen and the window sash.

It will be noticed that the carlines at the corners 23 are rounded and, consequently, the upper roof sheet can be bent around this corner and extended to the lower roof. sheets, as shown, without forming any abrupt angles.

In Fig. 8, I have illustrated my invention as applied to a car roof of the ordinary steel construction. In this instance, the side plates 6 extend between the upper overhanging carlines and thelower sections of the carlines and have openings 1O at intervals and flangessurrounding the openings; the flanges being so formed that a screen 12: can be secured to the flanges. The window casing 21 is located between the inner and outer plates and this. casing has exterior flanges so that it can be secured by bolts or rivets to the said plates.

1. The combination in a car roof, having a clear story, of a series of carlines spaced apart andextending from one side of the car to the other, each carline being made in two sections, the upper section supporting the roof of the clear story and the lower section supporting the main roof, the upper section of the carline being bent at the corners and turned downto form the supports for the side of the clear story and secured to the inner ends of the lower carline. sections, the said side portions being of a greater width than the roof section; roof plates for the clear story extending over the upper carline and down on each side of the side v members; and roof plates for the main roof structure.

2. The combination in a car roof having a clear story, of a series of carlines shaped to conform to the roof structure consisting of upper and lower sections; an upper roof sheet extending over the top of the upper section of the carline and on each side thereof; and a lower roof sheet at each side of the car, the joint between the sheets being made at an angle where the lower section of the carline is connected to the side portions of the carline which form the sides, of the clear story.

3. The combination in a car roof, of a series of carlines spaced apart and shaped to form the clear story of a car, the upper section of each carline being bent down to form supports for the sides of the clear story, these sections of the carline being of a greater width than the roof portion of the upper section; and a roof sheet extending over the upper section of the carline and down ,on each side to the lower section and having a series of openings in the sides thereof and having inturned flanges around the openings; an inner plate having openings alining with the openings in the outer plates; and a sash located in the walls of the openings.

4. A roof carline for a car of the clear story type consisting of two lower sections tapered as shown and wider at the base than at the upper end; an upper section extending across the clear story and forming a support for the roof thereof and bent downat each side and connected to the lower secof two subscribing witnesses.
